My any% run a year ago have been Verified before but now have have been rejected, I am wondering when the rule change? thanks. https://www.speedrun.com/hollowknight/run/mk4wp03y

Use of any game modifications other than the explicitly allowed increased load time mod has always been banned, this is not a new rule. Looking at the audit log, it seems your run was originally verified by Paerux, who has been inactive for some time now, so it may be difficult to reach him for an explanation. My assumption is he simply did not notice that you were using a modified game. You are free to do more runs to get a time back on the leaderboard, so long as you do not make use of any mods. Apologies for not noticing this much earlier.
